HINGE.

Specification of Letters latent.

Patented Oct. 10, 1916.

Application filed February 4, 1916. Serial No. 76,098. I

T 0 all whom it may concern:

My invention relates to hinges in general,

but more particularly to hinges for doors and windows, and especiallythose for basement, windows.

Generally stated, the object of my invention is to provide a novel andimproved hinge of such construction that it will automaticallylockitself in open position, thus holding a swinging window, such as abasement window, in raised or open position, thereby obviating thenecessity of using a hook or other device to temporarily hold the windowin this position.

A special object is to provide a hinge of this character which can bemade-very economically from sheet-metal.

It is also an'object to provide certain de- -'tails and features ofconstruction tending to detail section on line 3-3 efficiency anddesirincrease the general this particular characability of a hinge ofter.

To the foregoing and other useful ends, my invention consists in mattershereinafter set forth and claimed.

In the accompanying 1 is an inside view of a basement window, showingthe two upper corners thereof provided with hinges embodying theprinciples of my invention. Fig. 2 is a vertical section on line 22 inFig. 1. Fig. 3 is an enlarged in Fig. 1.

As thus illustrated, the swinging window sash A can be ofany suitable,known'or approved character, such as those ordinarily used for basementwindows. The hinges for the two upper corners of this sash are similarlyconstructed, and a description of one will be sufiicient for both. Theone shown at the right in Fig. 1 comprises, for example, a sheet-metalbracket B having a portion 7) which is secured by screws to the windowdrawings :Figure frame, and which has its inner edge portion bentoutward at right angles thereto. This outwardly extending portion C isprovided with upper and lower slots 1 and 2, the former being curvedabout a center disposed between its two upper end portions, and thelatter having an edge 3 which is also curved The portion 03 is providedwith upper and about said center. The lower portion of the slot 2 is, itwill be seen, horizontal and extends straight backward from the curvededge 3 to the face of the plate section B, in the manner shown in Fig.3. The edge ofthis slot 2, which is directly opposite the edge 3, isprovided with a series of notches 4, three of these notches being shownin the drawings. It will be understood, however, that a suitable ordesired number can be employed.

The plate D is of sheet-metal and is s e. .1

cured flatwise to the swinging window sash, being provided at onevertical edge thereof with an out-turned portion d, and being secured inplace by screws 5, or by any suitable means. This right-angle portion 03is mmediately inside of the portion G, the two portions being paralleland close together.

lower pins 6 and 7, the pin 6 working in the slot 1 and the pin 7extending into the slot 2, whereby the sash is, in eifect, hinged andsupported at its upper corners. The pins 6 and 7 are so relativelypositioned that when the sash is closed, the pin 6 is held in the innerend portion of the slot 1, as shown in Fig. 2, and at such time the pin7 is near the in ner end of the slot 2, in the maner shown. At thistime, the depending portion 8, which separates the two ends of the slot1, engages thepin 6 and prevents the top of the sash from fallingoutward.

In opening the window, the lower edge of the sash is swung outward, andifit be de sired to open it very widely, the sash is raised to theposition shown in dotted lines in Fig. 2. In this position the pin 6 isin the outer end of the slot 1 and the pin 7 is resting in the uppermostnotch 4, whereby the sash is held in raised position. On the'other hand,if it be desired to only partially open. the window, then the sash israised to the position indicated in Fig. 3, for example,

thereby bringing the pin 7 into the lower- 100 most notch 4, andcausingthe pin-6-to .pass

more widely than 1s shown in Fig. 3, and a little less than is indicatedby dotted lines in 110 The middle notch 4 may en- Fig. 2. It follows,therefore, that no hooks or other retaining devices are necessary forholding the sash in raised or open position. The hinges 6 'aresuflicient for this purpose.

A catch E, of any suitable or desired character, can be employed forsecuring the lower edge of the sash in closed position, in the usual andwell-knownmanner.

It will be seen that the upper and rear slot 1 is U-shape in form, andthat the pin 6 is in the inner end of this slot when the windowis'closed, or when the pin 7 is at the bottom of the slot as shown infull lines in Fig. 2. However, when the window or other closure is open,then the pin 6 is in the outer end of this U-shape slot and the pin 7 isin one of the'notches ofthe other slot. When the window is closed, thepin 7 is slightly in rear of the pin 6, instead of being directly inline therewith vertically, so that when the two pins 6 and 7 are in thesame horizontal plane, as shown in dotted lines in Fig. 2, the saidwindow or closure'is then higher at its free or outer edge than it is atits hinged or inner edge, and in this position the window may be said tobe wideopen. The two slots 1 and 2 are formed concentrically, with theexception "of the straight lower portion of the slot 2, in the mannershown.

What I claim as my invention is 1. A hinge for holding a swinging clo- Asure in open position, comprising a bracketplate, and means secured onthe closure to engage said plate and hold said closure in raisedposition and permit swinging motion thereof about a plurality ofrelatively fixed axes which are movable to different points on saidplate during the general operation of raising and lowering said closure.

2. I A hinge for holding a swlnging closure in open pos1t1on, comprlslnga bracketplate, and means secured on the closure to engage said plateand hold said closure in raised position, said plate having a portionformed with concentrically curved slots, one

slot having one or more notches, said means.

including relatively fixed pins which slide in said slots when theclosure is opened or closed, said notch or notches engaging one pin tohold the closure in raised position.

3. A hinge for holding a swinging closure in open position, comprising abracket-plate, and means secured on the closure to engage said plate andhold said closure in raised position, said 1 plate havin concentricallyformed slots, one above and in rear of the other, the front slot having.one or more notches, the rear slot being U-shape, said means includingupper and lower pins which slide in said slots, the upper pin being inthe front end of said rear slot when the other pin engages a notch tohold the closure in raised position, and said upper pin being in therear end of said U-shape slot when the lower pin is at the bottom of thefront slot.

4. A hinge for holding a swinging closure in open position, comprisingabracket-plate, and means secured on the closure to engage said plate andhold said closure in raised position, said means including upper andlower pins, each of said pins forming an axis of tilting motion for saidclosure, the lower pin being slightly in rear of the upper pin to holdsaid closure with the free edge thereof higher than its hinged portionwhen the two pins are in the same horizontal plane.

Signed by me at Sterling, Illinois, this 29 day of Jan., 1916.
